No restriction on operations among lengths, stretches and numbers

1

How about restricting feasible operations among lengths, stretches and numbers? I personally think the followings would be sufficient (at least for use cases mentioned in : ``` length +(-) length...

Rounding of stretch/length with dt unit

1

I think the specification should touch on rounding of stretch/length with dt unit. For example, how should compilers resolve stretch `s` in this case? ``` qubit q[2]; stretch s; barrier...

Minor bugs in circuit timing section

2

- zero length seems not to be allowed. The definition of `length` says ``` Lengths are positive real numbers... ==> non-negative? ``` - Fig. 6b does not represent the sample...

Control flows within a scope of a stretch

1

Can we write the code like below? ``` stretch mid; length start = mid + lengthof(Y)/2; length end = mid + lengthof(X)/2; k = 1; while (2.5 * (lengthof(Y) +...

Why don't we extend `box`'s spec to have some directives that specify how to align instructions in it (as qiskit's pulse builder has)? For example, ``` #align-left barrier q; some_long_gate...

### Summary Fixes https://github.com/Qiskit/qiskit-aer/issues/1478 by adding support for BackendV2 in `PulseSystemModel.from_backend`. ### Details and comments Updates `PulseSystemModel.from_backend` so that it can create a pulse system model from BackendV2 by calling...

Cleaner specification for RB experiments

This commit introduces the following API breaking changes that make the specification of StandardRB and InterleavedRB simpler and clearer. - Make 2Q RB physical qubits direction aware This change allows...

Coherence limit error of gates with three or more qubits

### Summary Extend coherence limit error computation to handle gates with three or more qubits. ### Details and comments Deprecate the original function `RBUtils.coherence_limit` and reimplement it from scratch as...
